I don't want to use any chemicals or milling. 20 years ago at the Hamvention, I purchased some one-sided circuit board material, that had about 0.0035" copper clad foil. I was able to score it with a #11 x-acto blade knife and then actually peel the foil off the board with pliers. Its all gone now, and I'm looking for of this type of board material to buy. Anyone know of a vendor that sells it?(Again, I want to score & peel it manually, using NO chemicals and any milling)ThanksJan N8CBX

First do the scoring then heat the edge where you want to start lifting with the soldering iron; a little solder helps heat transfer.

Lift the edge with sharp pliers (or a sharp knife until you have enough for pliers to grip).

Now lift with the pliers and draw the iron tip back as the strip peels-off, keeping the heat in the angle where the strip is lifting from the board. The heat loosens the bond between the copper and the substrate.

This requires one hand for the iron and one hand for the pliers so the board should be held-down with a weight or clamp.

It takes longer to describe than it does to do; co-ordination of the heat and the lifting force is the key.

Sometimes the pliers aren't required; you can heat a small cut-out area then rub it with the iron tip and it will break free and stick to the tip.
